11 Claims.

This invention relates to window structures, particularly for railwaycars, buses, and the like, and has for its object a window frameconstruction by which the frame is readily mounted in the window openingand secured therein without fastening members or screws exposed on theinner or outer sides of the frame or the body in which the frame ismounted.

It further has for its object a means hereinafter pointed out forsecuring the frame of the window opening without exposed fasteningmembers.

It further has for its object a window frame with rounding corners andslidable sash therein with rounding corners, the frame and thesashinterfitting at the margins of the sash, and means by which the sashcan be demounted from the frame by sliding the sash out of the roundingcorners onto a removable section of the frame into a position, wherebythe sash and the removable section of the frame can be demounted orreplaced as a unit.

It further has for its object a frame including a demountable sectionalong one rail thereof, particularly between the rounding corners.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had w to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is a side elevation of a window structure embodying myinvention, contiguous portion of the structural body in which the windowis mounted being also shown. 1

Figure 2 is a sectional view on line 22, Figure 1.

Figure 3 is an'enlargedsectional view on line 3-3, Figure 1..

Figure 4 is an enlarged fragmentary isometric view of the window frame,the removable portion being shown as demounted.

The car body or structural body provided with a window opening may be ofany suitable form,

size and construction. It includes generally upper and lower rails I, 2,posts 3 and outer and inner facing sheets 4, 5. The rails I, 2 and posts3 are, in the illustrated embodiment of my (Cl. l8964) bottom 8 towardthe inner faces of the posts3 and rails I, 2.

9 and I designate the outer and inner side flanges of the channel. Theframe is also formed with an external circumferential flange H on theouter side thereof, which laps the car body around the window opening orlaps the margin of the sheeting 4. A suitable gasket I2 is interposedbetween the flange and the margin of. the sheeting 4. The frame isusually formed of extruded metal and bent into rectangular form withrounding corners. The frame may be of one piece or a plurality of pieceswelded together. It

is preferably of two pieces, one of which extends along the bottom rail2 and includes a removable section between the lower rounding corners,as will be hereinafter explained. The bottom 8 of the frame 7constitutes a portion which telescopes into the window opening and acircumferential flange I l forms a facing for the margin of one lateralside wall of the car body around the window opening.

It and I designate sashes slidably mounted in the frame.

r In the window here shown, these sashes are shown as slidablehorizontally in the frame, and when entirely closed, the outer stile i8of one sash laps the corresponding stile I! of the other sash midwaybetween the ends of the frame, as seen in Figure 2. The sashes H, l5 arealso here illustrated as provided with rounding corners for conformingrespectively. with the rounding corners at the opposite ends of theframe I. The frame I and the sash are formed with interfitting parts, asribs and grooves, the frame 1 being formed with ribs l8 and I9 whichalso extend around the rounding cprners from the bottom 8 of thechannel. The sash, as best seen in Figure 3, are formed with grooves 20for receiving the rib I'B or l9,the rib- I8 entering the groove of thesash I4 and the rib l9 coacting with the groove of the sash l5, and thegrooves or channels of the sash being provided with a fibrous U-shapedlining 2| for receiving the rib and holding the sash and the frame fromout of metal-to-metal contact.

The frame is held in the window opening by fastening members exposed oraccessible from the bottom 8 of the channel of the window frame I, sothat no fastening members or screw heads are exposed on the inner andouter sides of the window structure.

The frame is located in the window opening by having a head 24 havingflanges lapping the outer face of the side flange it! of the channel ofthe frame 7 and the outer face of the sheeting 5. The fastening membersor screws 25 extend through the bottom 8 of the channel, the leg 23 andinto the post 3, the heads of the screws being exposed on the bottom 8of the channel. The leg or strip 23 of the member 22 constitutes aportion telescoping into the window opening and lapping the telescopingportion or the bottom 8 of the frame member 1, and the head 24 of themember 22 serves as a flange lapping the margin of the lateral side wallof the car body around the window opening, opposite to the side lappedby the flange ll of the frame member i and forms a facing therefor. Thefastening screws extend through the lapping portions. Thus, the partsare assembled by telescoping the members 1 and 22 into the windowopening and finally fastening them together with the fastening screws.Usually, in assembling, the telescoping portion or bottom 8 of the framemember 7' is formed with screw holes and when the two members I and 22are brought into proper position, the holes in the lapping portion orstrip 23 of the member 22 are marked through the holes in the bottom 8and then bored out for receiving the screws.

The member 22 may be in the form of a rectangular frame with roundingcorners or may be made up of sections. It is preferably a single unit inthe form of a rectangular frame.

The frame I and the retaining member 22 constitute sections of acomplete window frame, the bodies of which telescope, one in the other,within the window opening, which sections are insertable in the windowopening from opposite sides of the opening with the bodies ortelescoping portions lying flatwise, one on the other, and securedtogether by screws passing throughthem.

The bottom rail of the window includes a removable section 26 locatedbetween the rounding corners. This section 26 is angular in crosssection and formed with an external flange H forming a continuation ofthe flange H and also with ribs i9 and l8 forming continuations of theribs l9, IS. The ribs I9, l8 extend into the grooves in the lower railsof the sashes. The section 26 overlies a base strip 21 angular in crosssection and having a flange 28 along its outer edge alined with theflange III. The base strip extends under the bottom of the channel atthe rounding corners and is secured to the bottom of the channel, as bywelding. The abutting ends of the flanges l0 are also welded together.The leg 23 of the retaining member 22 extends between the removablesection 26 and the base strip 21. The section 26 is secured in positionby screws 29 extending therethrough through openings 30 in the strip 21and through the interposed leg 23 and into the body structure. Thegasket l2 extends between the flanges H and the sheeting 4 over thebottom rail 2.

In operation, the sashes are moved to lap each other sufficiently sothat their over-all length is less than that of the removable section26. The removable section 21 placed with the ribs I9 l8 in the groovesof the bottom rails of the sashes N, l 5. Then while the sash is tilted,the grooves on the upper rail thereof are interfitted with the portionsof the ribs I 9, 18 on the upper rail of the frame. Then the sash, withthe removable strip 26 swung inwardly, as a unit, between ribs IS l8into alinement with the ribs l8, l9 and the screws 29 applied. To removethe sash, the reverse of this movement takes place.

By this construction, a rectangular sash with rounding corners isprovided which interfits throughout the circumference of the sashleaving no cracks or crevices and also the sash can be readily demountedfor re-glazing or for repairing. Furthermore, the frame constructionconsists of a few parts, as the channel 1, removable section 26,retaining member 22 and the screws, which screws are hidden or notexposed.
